Notable quote from this talk:

“But it’s not just my kid that’s being deprived of sleep. Sleep deprivation among American teenagers is an epidemic. Only about one in 10 gets the eight to 10 hours of sleep per night recommended by sleep scientists and pediatricians.”

Wendy Troxel – Senior behavioral & social scientist

It’s six o’clock in the morning, pitch black outside. My 14-year-old son is fast asleep in his bed, sleeping the reckless, deep sleep of a teenager.

I flip on the light and physically shake the poor boy awake, because I know that, like ripping off a Band-Aid, it’s better to get it over with quickly.

I have a friend who yells “Fire!” just to rouse her sleeping teen. And another who got so fed up that she had to dump cold water on her son’s head just to get him out of bed. Sound brutal but perhaps familiar?

Every morning I ask myself, “How can I — knowing what I know and doing what I do for a living — be doing this to my own son?”

You see, I’m a sleep researcher. So I know far too much about sleep and the consequences of sleep loss. I know that I’m depriving my son of the sleep he desperately needs as a rapidly growing teenager.

I also know that by waking him up hours before his natural biological clock tells him he’s ready, I’m literally robbing him of his dreams — the type of sleep most associated with learning, memory consolidation and emotional processing.

But it’s not just my kid that’s being deprived of sleep. Sleep deprivation among American teenagers is an epidemic. Only about one in 10 gets the eight to 10 hours of sleep per night recommended by sleep scientists and pediatricians.

Eight hours is kind of like getting a C on your report card. There are many factors contributing to this epidemic, but a major factor preventing teens from getting the sleep they need is actually a matter of public policy. Not hormones, social lives or Snapchat.

Across the country, many schools are starting around 7:30 a.m. or earlier, despite the fact that major medical organizations recommend that middle and high school start no earlier than 8:30 a.m. These early start policies have a direct effect on how much — or really how little sleep American teenagers are getting.

They’re also pitting teenagers and their parents in a fundamentally unwinnable fight against their own bodies. Around the time of puberty, teenagers experience a delay in their biological clock, which determines when we feel most awake and when we feel most sleepy.

This is driven in part by a shift in the release of the hormone melatonin. Teenagers’ bodies wait to start releasing melatonin until around 11 p.m., which is two hours later than what we see in adults or younger children. This means that waking a teenager up at 6 a.m. is the biological equivalent of waking an adult up at 4 a.m.

On the unfortunate days when I have to wake up at 4 a.m., I’m a zombie. Functionally useless; I can’t think straight, I’m irritable, and I probably shouldn’t be driving a car. But this is how many American teenagers feel every single school day.

In fact, many of the, shall we say, unpleasant characteristics that we chalk up to being a teenager — moodiness, irritability, laziness, depression — could be a product of chronic sleep deprivation.

For many teens battling chronic sleep loss, their go-to strategy to compensate is consuming large quantities of caffeine in the form of venti Frappuccinos, or energy drinks and shots. So essentially, we’ve got an entire population of tired but wired youth.

Advocates of sleep-friendly start times know that adolescence is a period of dramatic brain development, particularly in the parts of the brain that are responsible for those higher order thinking processes, including reasoning, problem-solving and good judgment.

In other words, the very type of brain activity that’s responsible for reining in those impulsive and often risky behaviors that are so characteristic of adolescence and that are so terrifying to us parents of teenagers. They know that like the rest of us, when teenagers don’t get the sleep they need, their brains, their bodies and behaviors suffer with both immediate and lasting effects.

They can’t concentrate, their attention plummets and many will even show behavioral signs that mimic ADHD. But the consequences of teen sleep loss go well beyond the classroom, sadly contributing to many of the mental health problems that skyrocket during adolescence, including substance use, depression and suicide.

In our work with teens from LA Unified School District, we found that teens with sleep problems were 55% more likely to have used alcohol in the past month.

In another study with over 30,000 high school students, they found that for each hour of lost sleep, there was a 38% increase in feeling sad or hopeless, and a 58% increase in teen suicide attempts. And if that’s not enough, teens who skip out on sleep are at increased risk for a host of physical health problems that plague our country, including obesity, heart disease and diabetes.
